With respect, if you re-read the article you’ll discover multiple references to alternative organisations, small and large, that suppress and cover-up and casually brush away wrong-doing. My suggestion is in relation to those specific problems. In fact there is a hint in the article that a percentage of monies that flow to these alternative organisations should be used to tackle the problems of corruption. And the best way to do that, in terms of transparency and justice, is for the investigation to be carried out by a truly independent body. As sam plover points out, that independent body is also prone to corruption. That is why it must itself be independent, transparent, and reformed from top to bottom, every few years, lest it stagnates. I have no idea how to regulate and make indivividuals responsible other than through recourse to existing Laws that offer some protection to the vulnerable.
